Introduction
As we move deeper into 2024, the cybersecurity landscape continues to evolve rapidly, with ransomware attacks becoming more sophisticated and damaging than ever before. A particularly alarming trend is the surge in double extortion ransomware, where attackers not only encrypt an organization’s data but also exfiltrate it, threatening to release sensitive information unless a hefty ransom is paid. This tactic puts organizations in a precarious position, forcing them to consider not just the immediate operational impact of the attack but also the potential reputational damage and regulatory consequences of a data breach.
What is Double Extortion Ransomware?
Double extortion ransomware is a two-pronged attack strategy that combines traditional data encryption with data theft. Attackers first infiltrate an organization’s network, often through unpatched vulnerabilities or phishing emails, and then exfiltrate large amounts of sensitive data before encrypting the systems. The attackers then demand a ransom not only for the decryption key but also to prevent the stolen data from being published or sold on the dark web.
This method significantly increases the pressure on organizations to pay the ransom, as the cost of a data breach both financially and in terms of brand trust, can be catastrophic.
The Rise of Double Extortion in 2024
In 2024, we’ve seen a marked increase in the use of double extortion tactics. According to security experts, the number of postings to ransomware leak sites has nearly doubled, from an average of 24 per month in the first half of 2023 to 40 per month in the same period of 2024. This surge is driven by the profitability of these attacks and the relative ease with which cybercriminals can target unprepared organizations.
Groups like LockBit have been at the forefront of this trend, though recent law enforcement actions such as the FBI’s seizure of 7,000 decryption keys have disrupted their operations, leading to a temporary decline in their activities. However, the void left by LockBit is quickly being filled by other ransomware groups eager to capitalize on the lucrative double extortion model.
Notable Cases and Their Impact
One of the most concerning developments has been the rebranding of the SEXi ransomware group to APT INC, which continues to target high-value systems like VMware ESXi servers with sophisticated encryption tools. This group’s shift in tactics and targets highlights the increasing boldness of ransomware operators as they seek out more valuable and vulnerable assets.
In another significant case, the Daixin Team’s ransomware attack on Acadian Ambulance resulted in the theft of information on 10 million patients. The attackers demanded a ransom of $7 million, threatening to publish sensitive personal and medical records if their demands were not met.
Why Basic Cyber Hygiene is Still Failing Us
Despite the growing awareness of these threats, many organizations are still failing to implement basic cybersecurity measures. The lack of multi-factor authentication (MFA) and failure to patch critical vulnerabilities remain some of the most common entry points for ransomware attacks. Cybersecurity experts continue to stress the importance of these foundational defenses, but the persistence of these issues suggests that there is still a long way to go in educating and equipping businesses to fend off these increasingly sophisticated threats.

Conclusion
As ransomware tactics continue to evolve, so too must the defenses of organizations that wish to protect their data and reputation. Double extortion ransomware represents a significant escalation in the cyber threat landscape, and it is crucial that businesses not only understand the risks but also take proactive steps to mitigate them. Implementing basic cybersecurity practices, staying informed about the latest threats, and preparing a robust incident response plan are all critical components of a resilient cybersecurity strategy in 2024.
